get_closest_child_by_repr()

static SPObject * get_closest_child_by_repr ( SPObject &  obj, Inkscape::XML::Node *  ref  )

static

Get closest child to a reference representation.

May traverse backwards until it finds a child SPObject node.

Parameters

obj	Parent object
ref	Reference node, may be NULL

Returns

Child, or NULL if not found

sp_object_compare_position()

int sp_object_compare_position	(	SPObject const *	first,
		SPObject const *	second
	)

Compares height of objects in tree.

Works for different-parent objects, so long as they have a common ancestor.

Returns

*    0    positions are equivalent
*    1    first object's position is greater than the second
*   -1    first object's position is less than the second

sp_object_ref()

SPObject * sp_object_ref	(	SPObject *	object,
		SPObject *	owner = nullptr
	)

Increase reference count of object, with possible debugging.

Parameters

owner

If non-NULL, make debug log entry.

Returns

object, NULL is error.

Precondition

object points to real object

Todo:

need to move this to be a member of SPObject.
